I am running a RHEL server via a VM on my laptop. I have a win7 desktop sharing out a folder and the VM on my laptop running RHEL6 has a CIFS windows mount at \mnt\win When I go to unmount the device I get a device is busy message. So I went to my laptop and check to see if there were any users connected to the share, since it listed none I turned off sharing. I went back to my RHEL instance and attempted another umount \mnt\win but received the same error.


What are other alternatives to unmounting a shared drive?

umount -lf /mnt/win

If /mnt/win is not being used, umount will wait until it can unmount it.

Also, if you are in the mounted directory that's considered to be "in use." Change directory to outside the mounted path. – Aaron Copley Aug 30 '12 at 17:01
It never unmounts just sits there forever. @AaronCopley I have tried that as well – What'sTheStoryWishBone Aug 30 '12 at 20:28
